Vent-Axia 499883 Lo-Carbon Sentinel Econiq S MVHR Unit with Smart App Control

Product Description

The Vent-Axia 499883 Lo-Carbon Sentinel Econiq S MVHR Unit is an advanced Mechanical Ventilation with Heat Recovery (MVHR) system designed to deliver energy-efficient whole-house ventilation, excellent indoor air quality and year-round comfort. Developed and manufactured in the UK, this compact heat recovery unit combines intelligent ventilation controls, high thermal efficiency and ultra-quiet operation, making it ideal for modern new-build homes and energy-efficient residential properties.

Part of Vent-Axia's flagship Sentinel Econiq range, the unit benefits from advanced airflow engineering and high-efficiency motor technology to minimise energy consumption and operating noise. The range offers thermal efficiencies of up to 93% and breakout sound levels as low as 15.5 dB(A), independently tested and verified by SRL.

Featuring the innovative Sentinel-X wireless control platform, the Econiq S provides intelligent smartphone control through the Vent-Axia Connect app for iOS and Android. Homeowners can conveniently adjust ventilation settings, manage airflow and optimise comfort according to changing indoor conditions.

The integrated humidity sensor automatically responds to rising moisture levels, helping reduce condensation and maintain a comfortable indoor environment. Additional features include automatic frost protection, summer bypass functionality and an Approved Document F aligned commissioning wizard for straightforward installation and system setup.

Supplied with ISO Coarse 60% (G4) filtration as standard, the Sentinel Econiq S also supports optional ISO ePM10 (M5) and ISO ePM2.5 (F7) filters for enhanced airborne particle filtration.

High-Efficiency Heat Recovery Ventilation

The Sentinel Econiq range is engineered to recover heat from extracted indoor air and transfer it to incoming fresh air, helping reduce ventilation-related heat loss. With thermal efficiencies of up to 93% across the range, the system supports energy-efficient heating and comfortable indoor temperatures.

Advanced Computational Fluid Dynamics (CFD) engineering has been used to optimise internal airflow pathways, reducing resistance and helping the unit deliver effective ventilation with minimal energy consumption.

Smart App Control with Sentinel-X

The integrated Sentinel-X wireless control platform provides convenient management of the ventilation system through the Vent-Axia Connect smartphone application.

Homeowners can adjust ventilation rates to suit different conditions, such as increasing airflow during warmer periods or reducing ventilation to appropriate levels when the property is unoccupied. Compatible wired and wireless sensors can also be integrated to support demand-controlled ventilation.

Advanced Indoor Air Quality Filtration

The Vent-Axia Sentinel Econiq S is supplied with ISO Coarse 60% (G4) filters, designed to capture larger airborne particles such as dust, hair and other coarse contaminants.

For properties requiring enhanced filtration, optional ISO ePM10 (M5) and ISO ePM2.5 (F7) filter options are available. These provide additional filtration of smaller airborne particles, including fine dust and pollen, helping maintain cleaner incoming air.

Regular filter inspection and replacement according to the manufacturer's recommendations helps maintain airflow performance, filtration effectiveness and system efficiency.

Intelligent Humidity Control

The integral humidity sensor automatically increases ventilation speed in proportion to relative humidity levels. It can also respond to rapid increases in moisture, helping remove humid air from bathrooms and other wet areas before excessive condensation develops.

A night-time humidity setback function helps reduce unnecessary boost operation caused by gradual changes in relative humidity as indoor temperatures fall.

Ultra-Quiet Acoustic Performance

The Sentinel Econiq range incorporates carefully designed internal airflow channels, acoustic insulation and anti-vibration motor mounting to minimise noise transmission.

With independently verified breakout noise levels as low as 15.5 dB(A) across the range, the system is designed to provide discreet ventilation in residential environments. Optional acoustic enclosure and acoustic top box accessories are available for additional noise reduction.

Automatic Summer Bypass & Frost Protection

Integrated summer bypass functionality helps improve comfort during warmer conditions by allowing suitable incoming air to bypass the heat recovery process when beneficial.

Automatic frost protection helps protect the heat exchanger and maintain reliable system operation during cold weather. These intelligent functions support comfortable and efficient ventilation throughout the year.

Easy Installation & Commissioning

The Vent-Axia 499883 features 125mm duct connections and selectable left-hand or right-hand configuration through the unit controls, providing flexibility for different installation layouts.

The Approved Document F aligned commissioning wizard guides installers through the setup process, helping achieve the required ventilation settings for the property.
